i've got a site can use google's openid for login .
initially when i first time login it user the entire domain ( www.qigu365.com ) by goole openid , i'll login it ,and be a brand new user. and each time i've not a problem by login use www.qigu365.com, however when i login with qigu365.com ,i'll have problem , the website will stated i had been a brand new user , and allow me to fill my title .

how do i solve this issue ? i personally use ngnix rewrite function before to resolve this issue before , however i will poll time the customer towards the site.
